A transcription factor, LuxR (''<partinfo>C0062</partinfo>'') that is active in the presence of cell-cell signaling molecule [[3OC6HSL|3OC<sub>6</sub>HSL]] is controlled by a TetR (''<partinfo>BBa_C0040</partinfo>'') regulated operator (''<partinfo>BBa_R0040</partinfo>''). ''Device input'' is [[3OC6HSL|3OC<sub>6</sub>HSL]]. ''Device output'' is [[PoPS]] from a LuxR-regulated operator.  If used in a cell containing TetR then a second input signal such as [http://openwetware.org/wiki/ATc aTc] can be used to produce a logical AND function.  Get the pdf datasheet  [[:Image:EndyFig1-F2620DataSheet.pdf|here]].
